1 SPECIFICATION forming part Of Letters Patent N 0. 571,135, datedNovember 10, 1896.

' Application filed July 29, 1896. Serial No. 600,895- (No model.)

To all whom it may concern:

Be it known that I, J AMES MAHEDY, a citizen of the United States,residing at Kellerton, in the county of Ringgold and State of Iowa, haveinvented certain new and useful Improvements in Heaters; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention has relation to improvements in auxiliary heaters forstoves, and the object is to provide a simple, cheap, and convenientheater for ordinary wood and coal burning stoves; and to this end thenovelty consists in the construction, combination, and arrangement ofthe same, as will be hereinafter more fully described, and particularlypointed out in the claim.

In the accompanying drawings the same figures of reference indicate thesame parts of the invention.

Figure 1 is a perspective view of my improved heater as it appearsconnected to an ordinary stove, and Fig. 2 is a longitudinal section ofthe heater detached from the stove.

1 represents an ordinary stove, and 2 the inlet in the chimney or flue.

3 is the heater, and it consists of a horizontal cylindrical shell 4.and a depending vertical cylindrical chamber 5, secured thereto at itsupper end about midway of the shell 4. The front end 6 of the horizontalshell 4. is connected to the draft-pipe 7 of the stove 1, and itsopposite end Sis connected to the flue or chimney 2. A smallercylindrical pipe 9 is secured at one end to the flange 10 of the end 8,extending centrally inside of the shell at to within a short distance ofits opposite end 6, so as to leave a space between the end of the pipe 9and the flange 12 of the shell 4 about equivalent to the area of thepipe 9, which is about the same as the area between the outside of saidpipe and the inside diameter of the shell 4.

Depending from the pipe 9 and communicating with it internally is avertical pipe 13,

located inside of the chamber 5 and extending downwardly to within a fewinches of its end.

14 is a shaft extending through the pipe 9 and shell 4., and mounted onsaid shaft, inside of the pipe 9, is an ordinary damper 15, which may beoperated to open or close the passage in said pipe by a handle 15. Thelower end of the chamber 5 is provided with a removable cover 17, bymeans of which access may be had to the interior of the pipe 13 andchamber 5 to remove the soot and ashes.

18 18 represent the legs which serve to support the weight of the heaterwhen attached to the stove.

The cover 16 is provided with an orifice 19, normally closed by abalance-disk 20, mounted on the end of a lever 21, fulcrumed in the sideof the conical perforated hood 22.

When the damper is in position, as shown in Fig. 2, the draft from thestove passes direct to the flue through the horizontal pipe 9; but ifthe damper be partially or wholly closed a part of or the entire draftpasses around the outside of the pipe 9, down the chamber 5 on theoutside of the vertical pipe 13, thence upwardly through the interior ofthe pipe 13 into the horizontal pipe 9, and thence outwardly into theflue.

When there is a strong draft, the disk 20 will open inwardly and drawthe heavy, damp, and foul air from the room.

Having thus fully described'my invention, what I claim as new anduseful, and desire to secure by Letters Patent, is

A heater, comprising the horizontal $116114, the chamber 5, connectedtherewith, the horizontal pipe 9 located in said shell 4., and providedwith the damper 15, the vertical pipe 13 located in said chamber andcommunicating with said horizontal pipe, and the cover 17, removablysecured to the lower end of said chamber, and provided with the orifice19, the conical perforated hood 22, and the lever 21 mounted in the sideof said hood and provided with the disk 20, substantially as shown anddescribed. I

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
